Following query was executed but we are getting wrong sum for qty (SUBBL)
Query
select d.ccd,sum(d.qty),sum(f.qty) from
(Select distinct a.ccd,a.subbl,a.qty from subbl A, bl B, voy C
Where a.bl = b.bl and b.vcn = c. intvcn and c. vcn = 'TEST') D,subbl E, dcd F
where d.ccd = e.ccd and d.subbl = e.subbl and d.subbl = f.subbl
group by d.ccd
Result
CCD SUM(D.QTY) SUM(F.QTY)
C1 420 175
C2 20 20
Expected result
CCD SUM(D.QTY) SUM(F.QTY)
C1 220 175
C2 20 20

Hi,
This query is OK with you.
But i don't know why you use distinct in first inline view
select d.ccd,sum(d.qty),sum(f.qty) from
(Select distinct a.ccd,a.subbl,a.qty from subbl A, bl B, voy C
Where a.bl = b.bl and b.vcn = c. intvcn and c. vcn = 'TEST') D,
(select subbl,sum(qty) qty from dcd group by subbl) F
where d.subbl = f.subbl
group by d.ccd
Bye
